Serial No. 525,863.

I '0 all whom it may concern:

Be it known that I, Louis Iiinnn, a citizen of the United States, and a resident of Suinmithill, in the county of Carbon and State of Pennsylvania, have invented a new and Improved Siphon, of which the following is a full, clear, and exact description.

This invention relates to siphons for drawing off fluids from containers, and relates more particularly to siphons having means for preventing the accumulation, due to leakage or other causes, of air within the siphon, between the inlet and the outlet.

The object of the invention is to provide a simple, strong and durable siphon by means of which fluids of different kinds can be drawn from vessels or other containers, in accordance with the well-known principle of the siphon, in which the accumulation of air within the siphon tube is prevented, and which is continuous and certain in operation.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views, and in which Figure 1 is a side elevation of an e1nbodi ment of my invention; and Fig. 2 is a front elevation of the device.

Before proceeding to a more detailed explanation of my invention, it should be understood that the device is based upon wellknown principles of siphon action, according to which it is possible to effect a flow of fluid from a vessel over an edge of the same, owing to the fact that if a bent tube having one leg inserted in the liquid within the vessel is first filled with fluid and the same allowed to flow therefrom, a continuous flow of the fluid from the vessel will result if the outer leg of the bent tube is longer than that inserted in the vessel. However, I have found that the fluid passing through the tube tends to carry into it particles of air which accumulate within the crown or the upper part of the tube, and, if the ac from time to time, removing the accumulations of air, as will appear more clearly hereinafter.

Referring more particularly to the drawings, I provide a siphon fashioned from metal piping or other suitable conduit me1n bers, and having an inlet 10 and an outlet 11. These have respectively, associated there with, joints or fittings 12 and 13, consisting of Y-shaped unions. U-shaped tubes or conduits 14 and 15 are connected with the inlet and the outlet by means of the fittings 12 and 13. The conduit 15 is longer than the conduit 14 and extends to a higher elevation, as is clearly shown in the drawings. The conduit 14 has a manuallyoperable valve 16 of any suitable type associated therewith, so that the flow of fluid through the conduit can be controlled. The conduit 14 constitutes the siphon passage proper, while the conduit 15 is a bypass therefor. The conduits 14 and 15 have T-fittings 17 and 18 respectively, which are connected by a suitable pipe 19, for a purpose which will appear hereinafter.

After the flow of fluid through the siphon has begun, both conduits 14 and 15 will be filled with fluid. Air entering with the fluid, or entering through the joints of the passages or conduits, tends to accumulate in the upper parts of the conduits 14 and 15. However, as the conduit 15 is higher, 2'. 6., extends to a higher level than the conduit 14, the air within the latter will escape through the pipe 19 and be retained within the conduit 15. It will be noted that the pipe 19 communicates with the conduit 14 at the highest point, or the crown, thereof. In this way an unbroken and continuous stream of fluid is maintained through the conduit 14. After the conduit 15 has become completely filled with air, air will also begin to accumulate within the conduit 14. The valve 16 can then be closed so that a solid stream of fluid passes through the conduit 15 and carries away the air accumulated within the same. Thereupon the valve 16 is opened and the flow through the conduit 14 again begins. Thus, by operating the valve 16 at suitable intervals, a continuous, unbroken flow of fluid through the siphon can be maintained.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent 1. A siphon, having an inlet and an outlet,

and a bypass between said inlet and said outlet, and a further connection between said by-pass and the siphon.

2. A siphon, having an inlet and an outlet, a plurality of passages between said inlet and said outlet, a further passage connecting said first passages, and a valve for controlling the flow of fluid through one of said first passages.

A siphon, comprising an inlet, an outlet, a plurality of passages between said inlet and said outlet and connnunicating therewith, a further passage connecting said first passages, and a valve for controlling the flow of fluid through one of said first passages, said first passages extending to different elevations.

4. A siphon, comprising a plurality of conduits extending to dilferent elevations, and of substantially U-form, a common inlet and a common outlet for said conduits, one of said conduits having a valve controlling the flow of fluid therethrough, and a fur-.

thcr conduit connected with one of said first conduits at the crown thereof and communicating with the other of said conduits.

A siphon, comprising a plurality of conduits extending to different levels, and of substantially Uform, a common inlet and a common outlet for said conduits, the lower of said conduits having a valve controlling the flow of fluid therethrough, and a further conduit connecting said first conduits and extending from the crown of the lower of said conduits to the higher of said conduits, below the crown thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
